$30 for a cheap spark plug, porting does nothing, and apparently expansion chambers don't work. Oh and be sure to use the cheapest oil so your wrist pin bearing flies apart! I guess kids these days learn so fast that they become an engine tuning expert by slapping a cheap engine on a bike and calling it a day.

TAKE A SCRATCH AWL, OR A NAIL (DAMN CAPS LOCK) Stick it into yout intake port and trace out the upper part of the port onto your skirt.
Try the motorbicycling.com google custom search, this info is there in more detail.

This will likely give you a little too much inlet open time.
It should really be set at 60 deg ATDC.
And I didn't understand the 'Aussie Dialect' either, Mind you I don't text.

If you don't understand porting, DO NOT go after your engine with a dremel.
Do your research first or you risk a ruined or crappy running engine.
That being said, if you are careful and read up first, porting a chinagirl is easy. You can expect better power when porting is done properly.
